August

Although August is the month of holidays and high summer, it is also when the garden can start to become a little careworn. Actually this fading tendency tends to be worst at the beginning of the month and as we go towards September – at Longmeadow at least – it seems to pick up pace again. But it is mostly foliage that is tired whereas the intense colours of the late-flowering herbaceous plants like Heleniums, asters and rudbeckias are as vibrant as anything earlier in the year and the tender cannas, bananas, zinnias, dahlias and gladioli really come into their own and hit their magnificent stride.

The late flowering clematis are towers of flower in our Jewel Garden and the warm (albeit increasingly shorter evenings) are made fragrant by the musty scent of the wonderfully opulent giant tobacco plant, nicotiania sylvestris. 

The grass borders shift from greens to a wider range of colours including purples and golds and are moving towards their autumnal gold and tawny shades. 

The vegetable garden has courgettes, sweetcorn, French and runner beans, lettuce, carrots, beetroot, chard, shallots, onions and the first maincrop potatoes. All the winter brassicas such as kale, cauliflower, cabbage and broccoli are growing fast and must be protected from pigeons and the caterpillars of cabbage white butterflies.

In the greenhouse August is the month when chillies, aubergines, melons,  and tomatoes have their best fruit and add a state of sunshine to our northern table. Outside autumn-fruiting raspberries take over from the summer ones that quickly draw to an end and at the beginning of the month the blueberries are prolific and by the end the very first apples are ready to harvest although it is the end of September before most of our 62 varieties are really ready.

Hedge-cutting takes up a lot of our time and all the long grass is cut and where necessary reseeded with wild flowers.

RAPTORS

One of the features of August on the English Welsh border is the constant  and plaintive mewing of young buzzards (buteo buteo) learning to hunt for themselves. Although they have just left the nest and are only a few months old they are full grown but with the aeronautical skills of an ungainly chicken. They often land on the ground with an ungainly thump and then waddle about, catching little bigger than worms and beetles. Gradually they master the skies until by September they can soar high with their parents – which are never far away – and are catching bigger and more evasive prey.

Along side them we see Black Kites, looking especially for carrion although they are good hunters and the best and most valued summer visitor of all, the Hobby (falco subbuteo). This is the size of a kestrel but has the flying skills and appearance of a cross between large swift and an especially elegant and streamlined peregrine falcon. They cruise round the sky above the garden trying to pick off one of the many swallows and house martins which react to their appearance with massed hysteria, bunching and wheeling in a crowd of 40-50 strong to try and distract the Hobby. However their most common food are the dragonflies that they pluck and eat in the air and at dusk they will also comfortably catch bats, such is their incredible acrobatic skill.

What to do in the garden this month:

CUT LONG GRASS

If you have areas of long grass – especially if they are planted with bulbs like daffodils or crocus, they should have been left uncut to at least the beginning of last month to allow flowers to set seed and bulb foliage to die back. But August is a good month to cut a flowering meadow as short as possible. The aim is to expose areas of bare soil so that fallen flower seeds can make contact and germinate. 

This might mean hiring a powerful cutter or using a strimmer – although a scythe does the job as well as anything. Once the grass is cut it should all be raked up and put onto the compost heap (making sure that it is throughly dampened with a hose unless it is a very small amount). It is important to remove all cut grass as otherwise it feeds the soil as it decomposes and this will encourage lush regrowth at the expense of the wild flowers and bulbs. However, as long as the grass cuttings are collected,  it may be kept mown short right up until winter.

CUT HEDGES

It is safe now to trim hedges in the knowledge that the vast majority of nesting birds have fledged. Summer pruning results in slower, less vigorous regrowth than a winter trim so clip hedges to the height and shape that you wish them to remain for the rest of the year.  Start with the sides, making sure that you have a slight ‘batter’ or outward slope from the top to the bottom. This ensures that the lower section is not shaded by the top growth – which is always more bushy as it gets more light – and the hedge remains  fully ‘furnished’ right down to the ground. 

Finally, cut the top, using a string strung between canes as a guide. Deciduous hedge trimmings can be mown and added to the compost heap and evergreen ones taken to the council green waste.

DEADHEAD DAHLIAS

Dahlias will keep producing new flowers well into autumn as long as they are deadheaded regularly. The easiest way to tell the difference between a spent flower and an emerging bud is by the shape: buds are invariably rounded whereas a spent flower is pointed and cone-shaped. Always cut back to the next side shoot – even if it means taking a long stem – as this will stimulate new flowers and avoid ugly spikes of stem. 

And if you do not have dahlias then deadhead anything and everything daily – nothing else is so effective in keeping summer flowers from lasting as long as possible. 

TOMATOES

Tomatoes are coming up to their prime harvesting period but to extend this and make sure that all the current green tomatoes fully ripen  over the coming month or so there are a few things the tomato grower should do now. The first is to strip off the bottom half of the leaves on each plant. This will let in light and air so that the growing fruits get more sun and also he extra ventilation will reduce the risk of disease. This process can be continued weekly until there are no leaves left at all. Reduce the watering unless it is very hot to avoid the fruit splitting but keep up a weekly feed of liquid seaweed or, if you can make it, home-made comfrey feed. Both are ideal for maximising flower and fruit production. 

TAKE CUTTINGS

As August progresses semi ripe cuttings taken from current season’s wood that has started to harden off  are increasingly available and also increasingly likely to root quickly. In principal it is best to take cuttings in the morning whilst the plant is full of moisture but in practise it is something best done as and when you are minded to do it.

Always choose healthy, strong, straight  growth free from any flowers or flower buds. Once you have taken material from the plant  and placed it in the polythene bag  go and pot them up immediately. 

Strip off all lower leaves and side shoots so that only an inch or less of foliage remains. Cut the bare stem to size with a sharp knife or secateurs and bury it in a container of very gritty or sandy compost. 

Put this somewhere warm and bright but not on a south-facing windowsill as it may scorch. Water it well and then keep it moist with a daily spray from a hand mister  to help stop the leaves drying out before new roots have time to form. You will know that the roots have formed when you see fresh new growth. At that point the cuttings can be removed from the pot and potted on individually before planting out next spring. 

MAKING NEW STRAWBERRY PLANTS

After the early strawberries finish fruiting – usually the middle of July – they put their energy into producer new plants via runners. These are long shoots with one or more plantlets spaced along their length. As the plantlets touch the soil the put down roots, establish quickly and so the plant regenerates itself. By pinning them to the soil or onto a pot with compost in it and then separating it from the mother plant these can be harvested as new plants that will have more vigour than the parent and keep your stock replenished and refreshed. I dig up and compost the parent plant after four years as their productivity rapidly declines after this and they often accumulate viruses. 

By the end of August the rooted plantlets are ready for planting out into a new bed that has had a generous amount of compost added to it as strawberries are greedy feeders (they should always be planted on soil that has not grown strawberries for at least three years to avoid possible viruses). Space these at least 12 inches apart and ideally twice that to allow for maximum growth and productivity. Keep them well watered and mulch with more compost in autumn.

SOWING AUTUMN SALAD CROPS

Sow hardy salad crops such as ‘Rouge d’hiver’ and ‘Winter Density’ lettuce and Corn Salad, Rocket, Land Cress, Purslane, Mizuna and Mibuna. Make one sowing now for harvesting in October and November  and another in a month’s time that will crop in the new year if grown under cover. Either sow them into plugs that can be transplanted as seedlings or sow direct in rows. Thin the seedlings as they emerge and keep them weeded and well-watered.

PRUNING LAVENDER

To avoid woody, leggy plants, lavender should be pruned every year. The best time to do this is as soon as the flowers start to fade, which, depending on the variety, can be any time between midsummer and the end of August. But do not wait for the seed heads to form or the flowers to turn brown as you want to allow the maximum amount of time for regrowth before winter. 

Cut back hard to a good compact shape but be sure to leave some new shoots on each stem – lavender will often not regrow from bare wood. These new shoots will grow fast and provide an attractive and healthy cover to protect the plant in winter and provide the basis of next year’s display. 

COLLECTING SEED

Growing your favourite plants from seed is easy and practically without cost. Not only will this give you dozens of free plants for future years but also spares to give or swap with friends and family and August is the  time to begin collecting seed from your garden. 

Use brown paper envelopes – A5 is the idea size – and either carefully cut the seed heads and upend them into the envelopes, seed head and all or else place the envelop over the seed head, seal it and then snip the stem off and store it upside down. Label each envelope clearly with the date, name of the plant and, ideally, the position in the garden, and store them in a cool, dry place. 

After a week or two the seeds should be dry and can them be sieved, cleaned and stored in sealed packets. For longer term storage a plastic tub with a tight lid stored in the fridge is ideal.

WATERING CAMELLIAS, AZALEAS AND RHODODENDRONS

Camellias, Azaleas and rhododendrons form their flower buds in late summer and autumn. In other words the display that they give you next Spring is largely determined over the coming weeks. If they are too dry the buds will not form properly and those that are made quite often subsequently drop off in the spring before flowering as a result of dehydration the previous autumn. So give them a good soak  – with rainwater if at all possible – especially if they are growing in a container, and do so each week for the next couple of months.

July

Whereas July 2018 was part of a long hot, dry spell, this year Longmeadow starts the month sodden after a particularly wet June. But, by British standards at least, July is always warm so midsummer rain means lushness and green everywhere along with the intense colours of the high summer borders. The biggest problem of this is that everything has to be staked and supported because not only does the rain batter and weigh down flower and foliage, but it also encourages masses of soft, sappy growth. The upside is that it is lovely!

 The roses do not like the weather but the first half of the month is when they are at their best, from the old-fashioned shrub roses in the Cottage garden to the rambling roses hanging in swooping swags from the branches of the apple trees in the orchard. The more we dead-head, the longer we can extend their season into July but by the end of the month most have done their work and are finished.

The garden shifts into another gear. The light becomes thicker and although the days are drawing in from their June extremes, the evenings are still long and warm and all the plants such as dahlias, agapanthus, cannas, sunflowers and cosmos that all come from much closer to the equator, start to kick into their flowering stride and provide a whole new, richer palette to our borders.

The vegetable garden in July has lots of salad leaves, peas, beans, new potatoes, beetroot, garlic, carrots and artichokes and and tomatoes just beginning to bear fruit. The rhubarb and asparagus have their last picking at the beginning of the month and then are left to grow freely so goodness can be fed back to the roots to provide next Spring’s bounty.

Soft fruit is at its best with strawberries, summer raspberries, Tay and Logan berries, gooseberries, black and red currants and all ready for harvest.

Longmeadow is alive with song birds in July as most of the young fledged and explore their new territory, learning to fend for themselves before moving on later in the year.

What to do in the garden this month:

CUT BACK EARLY FLOWERING PERENNIALS

Early flowering perennials such as oriental poppies, delphiniums and hardy geraniums such as g. phaeum should all be cut back to the ground to encourage fresh regrowth and repeat flowering in a couple of months time. This also creates space for tender annuals and perennials in the border. Remove all cut material to the compost heap, weed around the base of the plants, water if necessary and do not plant too close to them so that they have light and space to regrow and flower again at the end of summer.

SUMMER PRUNING APPLES AND PEARS

Pruning apples and pears at this time of year in summer is very useful for trained forms like espaliers, cordons or fans or mature trees that have become too large or crowded because, unlike winter pruning, done when the tree is dormant, this hard cutting back will not stimulate vigorous regrowth.  Unless you are training a particular new shoot, remove all this year’s growth back to a couple of pairs of leaves (usually about 2-4 inches) being careful not to remove any ripening fruits.  If you are training the fruit to a particular shape,  tie desired but loose growth in as you go. Cutting it back now also allows light and air onto the fruit that is ripening and stops your trees becoming too crowded with unproductive branches.

STAKING

The extra warmth of July – and the wetness that comes with it – often leads to a flush of lush growth that plants cannot support. The result is that borders can start to fall all over the place, plants outgrowing themselves and toppling chaotically – especially if lashed by rain winds or thunderstorms and what was lovely profusion, can become a disaster zone overnight.

So it is good to have some brush wood such as hazel pea sticks or metal supports ready and to gently work round the borders easing plants upright and providing the underpinning that they need – but without reducing the border to a stiffly corsetted state that loses all the charm of midsummer bounty. Ideally it should not look as though you have done anything at all.

This can often apply to taller growing annuals such as ammi majus, sunflowers, cleome, Cosmos sensation, tithonias and Leonotis – all of which are stalwarts of Longmeadow. As these are planted individually it is hard to support them in the gently bolstering fashion that suits a large herbaceous perrenial, but they can be staked to half their height and tied with soft twine so that they can still move gently but not collapse completely.

CUT HEDGES

Young birds will have left their nests by now so hedges can be safely cut. A trim now will allow any subsequent regrowth to harden off before possible autumnal frosts.

Start by cutting the sides. Be sure to make the base of the hedge wider than the top – regardless of the height. This ‘batter’ allows light to reach the bottom half and ensures full, healthy foliage down to the ground. Then cut the top, using string as a guide to keep it straight and level. If it is an informal hedge, curve the top over so it is rounded.

If you have an overgrown hedge now is the best time to reduce it in size whereas if you have a hedge that needs reinvigorating, wait until winter and trim it hard when it is dormant. This will promote more vigorous growth next Spring.

If the hedge trimmings are not prickly they will be soft enough to chop up with a mower and added as a useful contribution to the compost heap.

PICKING RASPBERRIES

I would trade the very best strawberry for any raspberries and the summer fruiting varieties are at their best in July. Summer-fruiting raspberries carry their fruit on the canes that grew the previous summer – so all the fresh growth made in the current year will crop next July – whereas autumn-fruiting types such as ‘Autumn Bliss’ produce their fruit on the new-season’s growth. There is a freshness and seasonal treat to the summer raspberries that makes them especially good and we often pick a bowl just before supper and eat with a little cream whilst they are still warm from the evening sun. Heaven!

TOMATOES

It takes a hot summer for many of my tomatoes at Longmeadow to ripen before the very end of July but there is still a lot of tending to be done. Side shoots have to be nipped off almost daily – a job that I try and do first thing in the morning when I open up the greenhouse because the plants are turgid and therefore brittle and the shoots snap off satisfyingly easily.

We water the tomatoes just twice a week unless it is very hot and do not feed them at all in July. The compost added to the beds gives them the food they need at this stage and overwatering can cause the fruits to split.

The hotter it is the better the fruit will taste but it is important to have as constant a temperature as possible rather than great fluctuations between day and night so how much we open and close the windows and doors will vary a lot.  But ventilation is very important to decrease the risk of blight and viruses and as the month progresses I start to remove the lower leaves so that air and light can move around the plants and ripen fruit in the lowest trusses.

FEEDING CONTAINERS

Most plants grown in a container of any kind will exhaust the available nutrients from the compost they were originally planted as they grow and will need a regular supplementary feed for the rest of the summer. A weekly feed high in potash that will help promote root and flower formation (but not over-lush foliage) is ideal. I find liquid seaweed or a proprietary liquid tomato feed to work well.

The secret is to give just enough – and not too much. Too many nutrients is as damaging as too few as it causes rapid, lush growth – often at the expense of flowers or fruit – and which attracts extra fungal and predatory problems. Never be tempted to make the feed any stronger than the instructions dictate and if in any doubt reduce the strength. Your plants and displays will be the better for it.

PRUNING RAMBLING ROSES

It is very important to keep dead-heading roses as the petals fade to encourage repeat flowering, but some roses have now finished all that they are going to do this year. Most ramblers fall into this category, especially in the south of the country, roses such as ‘Wedding Day’, ‘Paul’s Himalayan Musk’ or ‘Felicite Perpetue’ should be pruned as soon as they have finished flowering. If you are in doubt as to whether your rose is a climber or a rambler, ramblers tend to be much more vigorous and always have a mass of small flowers that never repeat once they have finished.

Many ramblers are best grown into a tree and these can be left unpruned apart from straggly, unkempt,  growth. However if space is limited or you are training the rose in any way this year’s new shoots should be tied in or cut back according to the circumstance. Remove any damaged or very old shoots, cutting them right back to the ground.

If training round a vertical support it is best to wind the stems in a spiral. Otherwise, the more horizontal the stems can be trained, the more flowers will be produced next year.

Finally, tie in any loose growth and mulch well.

SOWING PARSLEY

I like to have a constant supply of parsley which can easily be done as long as you make successional sowings and now is the best time to sow the seeds that will provide plants for harvesting through winter and the first part of next spring. When the seed has germinated prick out the seedlings into individual pots or plugs and grow them on until large enough to plant out.

Do not be tempted to leave a sprinkle of seed that develops into a bunch of spindly seedlings but thin and encourage each individual plant to be strong. Space them at least 9 inches apart and allow each to became really vigorous. The well-spaced plants will have a big root and recover quickly from being cut back by throwing up more fresh leaves and thus provide a much better source of leaves for a longer period.

PICKING SWEET PEAS

Few garden chores can be as pleasant or undemanding as this but be sure to regularly pick all the flowers from your sweet pea plants is the best way to extend their flowering season. Sweet pea flowers will rapidly develop seed pods in warm weather and these drain energy from the plant and trigger more seed production at the expense of flowers. I have found that the optimum picking period for sweet peas is about 10 days. It is important to remove every single flower – and to enjoy the resulting fragrant bunches of blooms for the house.

Use scissors and cut the stems as long as possible and as soon as you see any seed heads remove them immediately. This way, in a cool summer, the plants can go on flowering right into September.

HARVEST GARLIC AND SHALLOTS

If the leaves are yellowing and seed heads are forming, this is a good indication that garlic and shallots (and onions too if they are ready, although they may need a few more weeks yet) are usually ready to harvest.  Always use a fork to carefully lift them rather than yanking them out of the soil by hand as you want to try and avoid damaging the roots and especially the root-plate – where they attach to the bulb.

Clean any surplus soil but do not remove any foliage or roots before putting them to dry thoroughly. This can be done by leaving them on the soil if it is dry and warm, on a home-made rack made from chicken wire stretched over posts or in a greenhouse. Once they are absolutely dry – usually after a few weeks – they can be topped and tailed for storage.

SUMMER PRUNING CURRANTS

After gooseberries, red and white currants have been harvested – which they all will by the end of July – it is a good idea to give them a summer prune. Remove any new growth that is crowding the centre of your bushes and cut back the new shoots you wish to keep by about a third. This will let light and air into the plant, encouraging the wood to ripen and spurs to form which will carry next year’s fruits.  Blackcurrants can be pruned hard – removing up to a third of each bush – immediately after harvest.

November

Although October is conventionally the month of turning leaves and brilliant colour, it is increasingly November that lights the autumnal torch brightest – at least in the first half of the month. But that leafy flame is becoming daily more fragile and the leaves stream to the garden floor with every wintry gust of wind. All these fallen leaves are gold dust and should be collected every last one to make leafmould which makes superb potting compost and is the ideal soil improver for all woodland plants and bulbs.

If November begins in autumn it ends unambiguously in winter. The days become shockingly short and the chances of frost – or worse – are real enough to make the business of protecting and tidying the garden urgent, so it is a busy month, especially as bad weather can bring work to a juddering halt for days or even weeks at a time. There is ground to be dug, deciduous hedges, trees and shrubs to be planted, tulips to be got into the ground and pots and the borders to be cleared and put to bed for the winter.

But for the gardener all November work is dictated by the weather. If there is a cold, clear spell then the days can be fresh and invigorating and much of the work of setting the garden to rest at the end of the year can be completed. In hope of these days I cut down as little as possible so that the dying stems can catch light and frost as well as provide cover and the seeds some food for birds.

But however positive I try and be, November is a low time of the year for me. December is little better other than it culminates in Christmas, which is fun. The days draw in like a noose and the garden seems to slowly implode, losing all the things that gave it worth. The only answer to this is to tend it dearly, looking after it like an ailing friend both to honour its better days and to prepare for the inevitable recovery in the New Year.

FROST

Frost always arrives at Longmeadow before the end of November – in fact this year we had frost in September and a few quite sharp frosts – down to -5 – in October. But even in a mild year there is no avoiding November frosts. I gathered in all the tender plants before the end of last month and protected those too big to move with a layer of fleece. I have one greenhouse wrapped up on the inside with a layer of bubblewrap and the other has a heater to keep the temperature above 5 degrees. That is enough to keep even the tenderest plant alive and well despite icy winds and arctic frosts all around it.

I am always happy when the ground rings under my boots like iron and the soil is locked intractably into position. It means that the cold is really working its magic for the garden. So what is that magic? After all, it is an unlikely benefactor. Less than 10% of the world’s plants are resistant to it, although a good number of those make up the majority of our British garden plants. However, it is like a purgative for the garden. Fungi, slugs, snails, viruses, insects, mammals like rats, mice and moles, even weak and damaged plants, all get blasted by it. Where it does not kill it does at least slow down proliferation. Just as a healthy person always feels better for a short fast or an icy plunge, so the garden seems to be healthier for a good freeze.

As long as you keep moving and there is not a strong wind blowing it is also surprisingly pleasant weather to work in. Frosty days are ideal for winter pruning – not least because you can stand on the soil without causing too much damage. The truth is that at Longmeadow there are only two kinds of winter weather, cold and dry or cold and wet. Give me cold and dry every time.

FEEDING BIRDS

There is a huge pleasure to be had from watching birds at a bird table and by putting out daily food you can greatly increase the chance of survival for many and subsequent breeding success, especially if it is a very cold winter. Once you start to feed try and be as regular as possible with the supply, as the birds use up precious energy in coming to your bird table which is then wasted if it is bare. Also always put a saucer of water out for them to drink.

Obviously it helps for the food to be as calorific as possible and seeds, nuts and fat are best of all. Left-over pastry, bread and rice always get eaten fast and fruit is good, especially for blackbirds and thrushes. Grated cheese is popular as well as cooked (but not raw) potatoes. Avoid anything salty such as crisps, salted peanuts or bacon. I buy dried mealworms too which robins, tits and wrens gobble up greedily. If in doubt sunflower seeds and fatballs – preferably hanging so tits can land on them without being bullied away by more aggressive birds – are invariably popular. Another way of making sure that all the food does not get gobbled up by pigeons and starlings is to find an old log with lots of cracks and crevices and pour seed over it. The smaller birds will extract every last bit from the fissures that bigger ones cannot reach.

One of the great joys of winter-feeding birds is that you can place the bird table right outside a window so you get a really good sight of them. Have a bird book or app to hand so you can identify them and I always have a pair of binoculars ready too. You don’t have to be a gardener or twitcher to enjoy the diversity and richness of these hungry winter birds, many of which you would never otherwise see, and the more you find out about them, the more fascinating they become.

What to do in the garden this month:

PLANT TULIPS

November is tulip-planting time. This is, to my mind, the most important and best job of the month. It is actually something that can be done at any time between now and Christmas although the earlier they get into the ground the earlier they will flower. The essential thing with all tulips is to make sure that they have good drainage. This matters less if they are to be treated as annuals and dug up after they have flowered but even so they will be happier with plenty of grit or sand added to heavy soil. If they are to be permanent it is important to plant them as deep as you can – I have done so using a crowbar before now to make a hole 12 inches or more deep – and the deeper they are the stronger and straighter the stem will be.

If you are growing them in a container then drainage is easier and they do not have to be so deep and can also be planted in layers – a tulip lasagne, with an earlier variety such as ‘Orange Emperor’ planted deepest that will flower first, followed by a mid-season variety like ‘Negrita’ planted above it and then finally, in the top layer a late-season one such as ‘Queen of Night’.

LIFTING DAHLIAS

Frost reduce Dahlias to blackened tatters so it will be time to bring them in. However the tubers will not be harmed unless the ground freezes, so do not panic. Wait until the top has fully died back and then cut back the top growth to 6 inches whilst they are still in the ground and carefully dig up the tubers, removing as much soil as possible. Stand them upside down for a few days to drain any moisture from the hollow stems and to let the tubers dry a little and then store them in a tray or pot packed with old potting compost, vermiculite, sharpsand or sawdust.

The idea is to keep them cool but frost-free, dark and dry but not to let them dry out completely or else the tubers will shrivel. I lightly water mine after layering them into large pots or crates and then check them every month to see if any are mouldy or shrivelling up.

LEAVES

Keep gathering fallen leaves, mowing them, keeping them damp and storing in a bay or bin bags to make leafmould. Leaves decompose mostly by fungal action rather than bacterial which means that dry leaves can take an awful long time to turn into the lovely, friable, sweet-smelling soft material that true leafmould invariably becomes. So either gather leaves when they are wet or be prepared to dampen them with a good soaking before covering them up with the next layer.

It also helps a lot to chop them up. The easiest way to do this is to mow them which also gathers them up as you do it. Of course if the leaves are too wet they will clog the mower up so I try and sweep and rake them into a line when dry, run the mower over them and then give them a soak with the hose when they are in the special chicken wire-sided bay. If you don’t have room for a dedicated leaf bay then put the mown leaves into a black bin bag, punch a few drainage holes in the bottom, soak them and let it drain and then store it out of sight. This system works perfectly well. Either way the leaves will quietly turn into leafmould over the next six months without any further attention. You can also use them in Spring in a half-decomposed state, as a very good mulch around emerging plants.

PLANT TREES, HEDGES AND SHRUBS

Continue to plant deciduous wood material such as trees, hedges and shrubs. From the beginning of this month nurseries will be selling bare-root plants. Buying woody deciduous shrubs, hedging plants or trees ‘bare-root’ – ie straight from the ground and not in a container – tends to be much cheaper, better quality and offers a much wider choice. But these must be planted when dormant so this is becoming a job that needs doing urgently. Plants in pots can wait a little longer if necessary.

As soon as you receive the plants give them a good drink in a bucket of water and keep them moist until ready to plant. Prepare your planting hole, remembering that a wide hole is much better than a deep one, and do not let the roots dry out even for a minute as they will die back very quickly so keep them covered or soaking in a bucket of water until the very last minute. Plant firmly, keeping all the stem above soil level, stake if necessary, water well and then always mulch thickly.

PLANTING PAPERWHITES FOR XMAS

Paperwhite daffodils, Narcissi papyraceus, will be flowering for Christmas if you plant them at the beginning of November. Unlike most daffodils, it is native to the Mediterranean and does not require a period of vernalisation – or cold – to induce flowering. So plant the bulbs just beneath the surface of your compost in a container (ideally with drainage but a normal bowl can be used if you add some charcoal to keep the soil sweet) keep them watered but not soggy and place in a warm, light place. The bulbs will grow strongly and if indoors in the warmth flower in 4 weeks. To delay and prolong flowering keep them cool but frost-free.

HARDWOOD CUTTINGS.

Hardwood cuttings are easy to take, slow to grow roots but a remarkably straightforward way of creating new shrubs, bushes and even trees from existing favourites. Fruit bushes, roses, any flowering shrub or tree are ideal for this method of propagation. Unlike growing plants from seed, cuttings always ‘come true’ – in other words they are exactly like the parent plant so it is the best way of reproducing favourite plants as well as being almost totally trouble free and needing no extra equipment or shelter.

Cut a 12-24 inch length of straight stem the thickness of a pencil of this year’s growth, and divide it into lengths between 6 & 12 inches long. Cut straight across the bottom and at an angle at the top so you remember which way up to plant it and to provide an angle for water to run off.

Strip any remaining leaves from it so you have bare, straight stems and either place the cuttings so only one third is above soil level in a deep pot filled with very gritty compost (4 or 5 can fit into each pot) or outside in a narrow trench backfilled with gritty sand to ensure good drainage. Leave them until next autumn, watering well once a week and a good percentage will make young plants ready for potting up or planting straight out.

WASHING SLIPPERY PATHS

At this time of year brick and stone paths can be very slippery and dangerous. This is due to algae that grows on the surface, especially if wet and shaded and at this time of year they may stay wet and slippery for months. The best way to reduce the slipperiness is to wash off the algae with a pressure hose (which can be hired by the day). When this is done brush in sharpsand. If the path is brick or stone the porous surface will absorb some of the sand. A quicker – but still quite laborious – alternative is simply to work sand in with a stiff brush without the washing. Either way you have a very effective way of making a path safe without resorting to chemicals.

 

October

October is a yellow month, with the Field maples, hawthorns and above all elm hedgerows blazing brilliant yellow before falling.  It is an earthy time with the smells of fruit, wormcasts, fallen leaves and woodsmoke sifting through the afternoon air.

There comes a moment in October when you realise that the garden is running out of steam. I like the way that the season can shift almost overnight in October with soft days glowing with light and midday sun warm enough for shirtsleeves and then blasts of weather that send you huddling for warmth and shelter.

However good the weather, you cannot avoid the evidence that the garden is drifting steadily into winter. Every sunny day is borrowed. The light – although often the softest and most golden of the whole year – is slipping away.

Every second of light is precious because finally, on the last weekend of the month, the clocks change and a door closes tight until next spring.

Despite the way that light, colour and human and plant energy are all on the wane, it is time to take stock and to plan ahead. It is not so much a time to put the garden to bed but to gently prepare it for action. The more that you can get done between now and Christmas to prepare the garden for Spring, the better it will be for you and the garden.

AUTUMNAL BIRDLIFE AT LONGMEADOW

The whole relationship between the garden and birds changes as soon as the leaves start to drop. For a start they are more visible. They crowd the branches as a series of shapes rather than sound then the outline of a small tree will suddenly fragment as a flurry of birds leave scared away from grabbing berries whilst they can.

It makes you aware of how present the soft midsummer sound of unseen birdsong is, how important an element in any garden. Winter bird sound is much harsher, a series of warnings rather than melodious love songs. Occasionally a Robin will astonish the afternoon with a clear burst of song, but a November afternoon in this garden tends to shuffle with staccato bird sound, like overhearing an argument in another room.

You know when winter is round the corner when the Fieldfares and Redwings arrive from their summer quarters in Siberia. They are heralds of the season just as surely as summer is certified by the first swallow. But the swallows arrive with a kind of soaring familiarity, reforming intimacy with the garden and the precise details of the house like a child returning home after weeks away. Fieldfares (Turdus pilaris) on the other hand are a curious mixture of awkward truculence and shyness. They look like large thrushes with handsome grey head, chestnut back, black tail and spotted underparts but are always seen in flocks, whereas the resident song thrushes are much shyer, more solitary birds – and have a much sweeter song.

Fieldfares rise in a clucking, chattering cloud if you so much as appear within their sight and yet are always pushing aggressively forward as soon as they think your back is turned. Everything about them is harsh and jerky. Yet I like them. They are of the season. They like the apples left in the orchard best of all and will fiercely defend a tree with windfalls from other birds. They also do a lot of good for the gardener, eating snails, leatherjackets and caterpillars.

The other winter thrush, the Redwing, is smaller, daintier and less intrusive. Whereas the fieldfare has an instantly recognisable mauvey grey head, the Redwing is only really distinguishable from a song thrush in flight when the red flash under the wing is very visible – although its tendency to flock, like the fieldfare, is also a giveaway. In the dead of the country night, in an otherwise silent pitch blackness I sometimes hear their thin rather ghostly flight calls as they fly overhead.

What to do in the garden this month:

SCARIFY LAWNS

A bit of work on your lawns now will be repaid many times next spring. Start by raking it hard with a spring-tine wire rake. This will remove a surprising amount of thatch and moss which can be put on the compost heap. Do not worry about bare patches – if large a little seed can be sprinkled on them but otherwise they will fill naturally.

Then aerate it to remove compaction. On a small patch, a fork thrust in as deep as possible every 9-12 inches will do the trick but you can hire aerating machines for a larger lawn that remove small plugs of soil.

When you have finished, brush any plugs or loose soil across the surface and if it is very compacted, also brush sharp sand into the holes you have made. Don’t worry if it looks rough –  it will quickly recover in time to face whatever winter can offer and start next spring in the best possible condition.

•   If you do not already posses them, invest in horticultural fleece and some cloches. The point is that these are only useful if you have and employ them before you need them and there is no guarantee that there will not be a hard frost in October. Cloches are very good for rows of vegetables, keeping them dry as well as warm (although I always leave the ends open – happy to trade some heat for some ventilation) and fleece is the best temporary protection against frost, either laid out over small plants or draped over shrubs and bushes.

•   Keep deadheading throughout October, particularly the equatorial plants like dahlias. This will extend their flowering season and squeeze the last bloom from them.

•   Save yourself a fortune by collecting seeds from perennial plants, using paper (not polythene) bags. Always label seed packets immediately. Store in a cool, dry place until ready for sowing.

•   It is not too late to take cuttings and there is no more satisfying process in the garden if it is successful. Choose healthy non-flowering growth, use a sharp knife and very free draining compost (I use 50:50 sharp sand and sieved leaf mould) and keep the humidity high. Most things will strike now and overwinter successfully without needing potting on.

•   It is worth taking trouble to store the fruit so that it lasts as long as possible. Only store perfect apples, which discounts nearly all windfalls. A cellar is ideal or a cool garage, but polythene bags, folded not tied and punctured with pencil holes work very well. Put the bags somewhere cool, dark and dry.

•   You can plant or move deciduous trees, shrubs and hedges even if they are still in leaf as they have finished growing and the soil is still warm so the roots will begin to grow immediately. I once moved a 4 year-old, 20 metre long hornbeam hedge in October. It never batted an eyelid and grew away the following spring stronger than ever. It is essential, of course, to give them a really good soak when you do so and to repeat this weekly until the ground is really wet or the leaves have fallen. But if you are planting or moving a number of trees or shrubs  It is best to start with any evergreens before deciduous plants as they need to maximise root growth before winter kicks in.

•   Plant or move biennials such as forget-me-nots, wallflowers, foxgloves, onorpordums and mulleins. Dig up healthy Verbena bonariensis, cut back and pot up to use to take cuttings next spring and take cuttings of penstemons and salvias.

•  Continue planting spring bulbs but wait another month for tulips.

SOW SWEET PEAS

By sowing sweet peas in October you will have bigger plants with a stronger root system that should give flowers next spring earlier and last longer. But the disadvantage is that these young plants will need storing and some protection over winter if the weather is bad. So I sow some now and another batch in February and spread the risk.

I sow three seeds in a three-inch pot although root-trainers also do the job very well. Use a good potting rather than seed compost. Put them to germinate on a windowsill or greenhouse and once the first leaves have grown, place outside in a cold frame or protected spot. They only need protection from hard frosts, mice and becoming sodden, so do not provide any extra heat. They will be ready to plant out in April.

•   Cut back and compost all rotting foliage in the borders but leave as much winter structure as possible.

•   Start digging any ground that you want to replant this winter or use next spring. Doing it at this time of year means that it is accessible, dry and there is more daylight to do it in! But if this seems daunting do 30 minutes a week in two 15-minute sessions. Leave the soil in large slabs for the weather to break down over winter.

•   If you have raised beds – and if not October is an ideal month for making them – mulch them with an inch or so of garden compost as they become clear, leaving the worms to work it in ready for sowing or planting next spring.

•   Unless the weather is bad, most leaves do not start falling until November but gather them all and store every last one – nothing makes for a better soil conditioner or potting medium. If you do not have somewhere to store them sort this out early in the month. A simple bay made from four posts and chicken wire is ideal.

•   Sow ‘Aquadulce’ broad beans outside for an early harvest next May or June and sow sweet peas in pots and over-winter in a cold frame.

•   Keep cutting the grass for as long as it keeps growing, however it is better to have the grass too long than too short over the winter months. Rake out thatch and moss and add to the compost heap.

•   Cut off any hellebore leaves that are obviously diseased and mulch around spring-flowering perennials with a 50:50 mix of last year’s leaf mould and garden compost.

PRUNE CLIMBING ROSES

Climbing roses flower on shoots grown the same spring so they can be pruned hard now. (Rambling roses on the other hand produce their flowers on shoots grown the previous summer so should only be pruned immediately after flowering.) Start by removing any damaged or crossing growth or any very old wood which can be pruned right back to the ground. The main stems should be fanned out at an equidistance as horizontally as possible, tying them to wires or a trellis. Then all the side shoots growing from these main stems – which produced this year’s flowers – can be reduced to a short stub of a couple of leaves. The effect should be a tracery of largely horizontal growth with pruned side-shoots running along their length. Finally make sure it is all tied firmly in to avoid winter damage

•   We give our deciduous hedges – hornbeam, hawthorn and field maple – a light trim in October which keeps them crisp right through the winter and looks really good when everything else has sunk into decline.

Finally, and most importantly, get outside and relish every second of October sun. It will be a long time gone.

 

 

 

 

July

As my birthday is in July, it marks the beginning and end of my personal year and certainly during the course of the month there is a seasonal shift and the garden changes. The easy, open lightness of June is replaced with a richer quality and this is played out in the borders where the colours all become stronger. The first half of the month belongs to roses although by the end mine are mostly finished. Sweet peas are usually at their most bountiful and dahlias, sunflowers, cosmos and the late clematis all start to get into gear.

The vegetable garden in July has peas, beans, new potatoes, beetroot, garlic, carrots, artichokes and tomatoes just beginning to bear fruit, and late meals eaten outside as the light gently falls around the garden.

July is also irrevocably associated with school holidays and time spent playing outside in the sun. Adults call that play ‘gardening’ but the sense of freedom and the pleasure of being outside on long hot days is just the same.

OWLS

The other day a tawny owl fell down the chimney in our bedroom and spent the day there, perching rather crossly on top of a cupboard before drifting out of the opened window at nightfall.

This garden rings to the calls of tawnies all the year but especially from late summer into autumn when the young are leaving to find their own territories. But for now and for the rest of summer they will remain close to the nest, learning to hunt and mastering their incredibly silent, dexterous flight. Some nights a silhouetted figure will perch on a wigwam of bean sticks in the garden and screech with shocking loudness before slipping anonymously away. For such a big bird tawny owls fly with the muffled softness of a snowflake. Their night sight is good but their hearing is astonishing and the slightest rustle will be unerringly located and the scurrying mouse clutched in their powerful talons before it has heard a thing.

When I was a boy at boarding school in the early 1960’s the matron adopted a young owl and it would sit on her head as she walked round the dormitories, nibbling on her grey hair and pulling it gently in its beak. One night it swooped through the open window and sat on the end of my bed, shifting its feet and looking round with its swivel head. Then, as suddenly and quietly as it came, it flitted, mothlike back out into the dark of the night.

You never forget such things.

What to do in the garden this month:

CUT BACK EARLY FLOWERING PERENNIALS

Early flowering perennials such as oriental poppies, delphiniums and hardy geraniums such as g. phaeum should all be cut back to the ground to encourage fresh regrowth and repeat flowering in a couple of months’ time. This also creates space for tender annuals and perennials in the border. Remove all cut material to the compost heap, weed around the base of the plants, water if necessary and do not plant too close to them so that they have light and space to regrow and flower again at the end of summer.

SUMMER PRUNING APPLES AND PEARS

Pruning apples and pears at this time of year in summer is very useful for trained forms like espaliers, cordons or fans or mature trees that have become to large or crowded because, unlike winter pruning, done when the tree is dormant, this hard cutting back will not stimulate vigorous regrowth. Unless you are training a particular new shoot, remove all this year’s growth back to a couple of pairs of leaves (usually about 2-4 inches) being careful not to remove any ripening fruits. If you are training the fruit to a particular shape, tie desired but loose growth in as you go. Cutting it back now also allows light and air onto the fruit that is ripening and stops your trees becoming too crowded with unproductive branches.

CUT HEDGES

Young birds will have left their nests by now so hedges can be safely cut. A trim now will allow any subsequent regrowth to harden off before possible autumnal frosts.

Start by cutting the sides. Be sure to make the base of the hedge wider than the top – regardless of the height. This ‘batter’ allows light to reach the bottom half and ensures full, healthy foliage down to the ground. Then cut the top, using string as a guide to keep it straight and level. If it is an informal hedge, curve the top over so it is rounded.

If you have an overgrown hedge now is the best time to reduce it in size whereas if you have a hedge that needs reinvigorating, wait until winter and trim it hard when it is dormant. This will promote more vigorous growth next Spring.

If the hedge trimmings are not prickly they will be soft enough to chop up with a mower and added as a useful contribution to the compost heap.

PICKING RASPBERRIES

I would trade the very best strawberry for any raspberries and the summer fruiting varieties are at their best in July. Summer-fruiting raspberries carry their fruit on the canes that grew the previous summer – so all the fresh growth made in the current year will crop next July – whereas autumn-fruiting types such as ‘Autumn Bliss’ produce their fruit on the new-season’s growth. There is a freshness and seasonal treat to the summer raspberries that makes them especially good and we often pick a bowl just before supper and eat with a little cream whilst they are still warm from the evening sun. Heaven!

TOMATOES

It takes a hot summer for many of my tomatoes at Longmeadow to ripen before the very end of July but there is still a lot of tending to be done. Side shoots have to be nipped off almost daily – a job that I try and do first thing in the morning when I open up the greenhouse because the plants are turgid and therefore brittle and the shoots snap off satisfyingly easily.

We water the tomatoes just twice a week unless it is very hot and do not feed them at all in July. The compost added to the beds gives them the food they need at this stage and overwatering can cause the fruits to split.

The hotter it is the better the fruit will taste but it is important to have as constant a temperature as possible rather than great fluctuations between day and night so how much we open and closes the windows and doors will vary a lot. But ventilation is very important to decrease the risk of blight and viruses and as the month progresses I start to remove the lower leaves so that air and light can move around the plants and ripening fruit in the lowest trusses.

FEEDING CONTAINERS

Most plants grown in a container of any kind will exhaust the available nutrients from the compost they were originally planted as they grow and will need a regular supplementary feed for the rest of the summer. A weekly feed high in potash that will help promote root and flower formation (but not over-lush foliage) is ideal. I find liquid seaweed or a proprietary liquid tomato feed to work well.

The secret is to give just enough – and not too much. Too many nutrients is as damaging as too few as it causes rapid, lush growth – often at the expense of flowers or fruit – and which attracts extra fungal and predatory problems. Never be tempted to make the feed any stronger than the instructions dictate and if in any doubt reduce the strength. Your plants and displays will be the better for it.

PRUNING RAMBLING ROSES

It is very important to keep dead-heading roses as the petals fade to encourage repeat flowering, but some roses have now finished all that they are going to do this year. Most ramblers fall into this category, especially in the south of the country and those such as ‘Wedding Day’, ‘Paul’s Himalayan Musk’ or ‘Felicite Perpetue’ should be pruned as soon as they have finished flowering. If you are in doubt as to whether your rose is a climber or a rambler, ramblers tend to be much more vigorous and always have a mass of small flowers that never repeat once they have finished.

Many ramblers are best grown into a tree and these can be left unpruned apart from straggly, unkempt growth. However if space is limited or you training the rose in any way, this year’s new shoots should be tied in or cut back according to the circumstance. Remove any damaged or very old shoots, cutting them right back to the ground.

If training round a vertical support it is best to wind the stems in a spiral. Otherwise, the more horizontal the stems can be trained, the more flowers will be produced next year.

Finally, tie in any loose growth and mulch well.

SOWING PARSLEY

I like to have a constant supply of parsley which can easily be done as long as you make successional sowings and now is the best time to sow the seeds that will provide plants for harvesting through winter and the first part of next spring. When the seed has germinated prick out the seedlings into individual pots or plugs and grow them on until large enough to plant out.

Do not be tempted to leave a sprinkle of seed that develops into a bunch of spindly seedlings but thin and encourage each individual plant to be strong. Space them at least 9 inches apart and allow each to become really vigorous. The well-spaced plants will have a big root and recover quickly from being cut back by throwing up more fresh leaves and thus provide a much better source of leaves for a longer period.

PICKING SWEET PEAS

Few garden chores can be as pleasant or undemanding as this but be sure to regularly pick all the flowers from your sweet pea plants as this is the best way to extend their flowering season. Sweet pea flowers will rapidly develop seed pods in warm weather and these drain energy from the plant and trigger more seed production at the expense of flowers. I have found that the optimum picking period for sweet peas is about 10 days. It is important to remove every single flower – and to enjoy the resulting fragrant bunches of blooms for the house.

Use scissors and cut the stems as long as possible and as soon as you see any seed heads remove them immediately. This way, in a cool summer, the plants can go on flowering right into September.

HARVEST GARLIC AND SHALLOTS

If the leaves are yellowing and seed heads are forming, this is a good indication that garlic and shallots (and onions too if they are ready, although they may need a few more weeks yet) are usually ready to harvest. Always use a fork to carefully lift them rather than yanking them out of the soil by hand as you want to try and avoid damaging the roots and especially the root-plate – where they attach to the bulb.

Clean any surplus soil but do not remove any foliage or roots before putting them to dry thoroughly. This can be done by leaving them on the soil if it is dry and warm, on a home-made rack made from chicken wire stretched over posts or in a greenhouse. Once they are absolutely dry – usually after a few weeks – they can be topped and tailed for storage.
